Although former Eagles cornerback Cary Williams called Chip Kelly a great coach, there was a huge "but" in there when he talked about his boss of two seasons in a radio interview on Tuesday.

Now a member of the Seattle Seahawks, who last December bludgeoned Williams and the Eagles in a 24-14 victory that was way more lopsided than the score, Williams was candid about how he believes Kelly's unusual in-season conditioning regimen, which includes Tuesday practices following Sunday games, backfired.

"We was talking [before the game] about the fact that our conditioning and things like was going to kick in because we worked harder than everybody in the National Football League with the Chip Kelly thing," he told 710 ESPN Seattle. "We got out there, we got our teeth kicked in. So all that conditioning didn't necessarily work. Preparation wasn't necessarily the greatest neither that week.

"When you're going up against teams that prepare well, practice well, coach well, it's difficult in games like that. I think towards the end of the year we were exhausted and we got outcoached the majority of the games."

That may sound like sour grapes from someone who just doesn't like to practice on Tuesdays, but could there be an element of truth to what Williams, who leveled similar criticisms while with the team last season, reiterated?

Consider that last season the Eagles were worse in all three December rematches against division opponents, losing key games to Dallas and Washington (after winning the first time around) and finishing with a hard-earned but meaningless victory over the New York Giants after crushing them 27-0 in their first meeting.

Major injuries, especially to starting quarterback Nick Foles, probably had more to do with it than anything. Yet there isn't definitive proof out there that what Williams said isn't right.

Furthermore, he said early last season that the players would often come out flat in games because they were overworked, forcing them to scramble and come from behind, like they had to do in consecutive wins over Jacksonville, Indianapolis and Washington to open the season, before losing at San Francisco.

In all, the Eagles trailed in early in half of their 10 victories. For what it's worth, they also coughed up leads in all but one of their losses.

But although they were forced to come from behind quite a bit in 2013 as well, they did finish the regular season strongly, which likely was the result of Foles and the offensive line staying healthy throughout.

Will Kelly tweak his in-season routine? Doubtful.

But it's something he at least has to examine again this offseason and possibly be ready to adjust as they go.
